I can't help but think some groups must have no good people just by virtue of what the group is. Good people don't join the Proud Boys or the KKK, nor can good people be billionaires.
I guess it would depend on what is considered a prerequisite. Those groups are best avoided whenever possible, but they know how to find themselves with people who join because they have to feed their families or something, and some join internally denouncing its worst aspects. By the same token, most people today (myself included) wouldn't automatically consider Muslims to be a "bad group" even though the Quran is still pretty intolerant.
Taylor Swift was always technically popular but surged in popularity following a few events where she sang. For about a few months, that's all anyone ever wanted to talk about, and there was even an infamous incident where mayhem was erupting in Canada while Justin Trudeau was at a Taylor Swift concert. In short, for those few months, she became one of those "overrated" people like we tend to think of Justin Bieber as.
Then came time for the Superbowl, and an unfortunate string of circumstances led to it being highly politicized (in the semifinals, the Buffalo Bills were cheated out of going to the Superbowl by referees who were biased towards the Kansas City Chiefs, and people were boycotting the Superbowl until the people there had the bright idea of having Donald Trump book a seat in order to boost ratings). Taylor Swift made an appearance at the Superbowl too, but the specific demographics of the Superbowl caused by the presidential gimmick they threw in ended up creating a crowd that disliked her and booed her, which in turn instantly popped the trend bubble. Which to be fair is unfair, she never asked for any of this and was just riding the wave so-to-speak until it came crashing down in an outburst of hate.
